The Aves and Big Hazard have had about 9 or ten members in the Mexican Mafia. I think Primera Flats has had about 7 or 8, but this gang has had about 15 guys become members of La Eme. Those three are good answers tho.

The answer is Hoyo Maravilla. Between 1957 through 1973 22 mafia members were from Maravilla and 17 from Hoyo Maravilla, 4 from Ford and one from Kern. At least two of The founding members of the eme were from Hoyo.
